The SFB/TR55 "Hadron Physics from Lattice QCD" was established
in July 2008 by the Deutsche Forschungsgemeinschaft at the
Universities of Regensburg and Wuppertal. It is currently coordinated
by Regensburg.

The research programme consists of three project areas.
A: Lattice QCD calculations of hadronic observables.
B: Algorithms for Lattice QCD simulations.
C: Development and deployment of the QPACE parallel supercomputer.

The results of project area A are required for
the interpretation of particle collider experiments such as
the LHC at CERN or the planned FAIR facility at Darmstadt. They also contribute to our understanding of the early universe.

Project area B is interdisciplinary in nature and
prominently includes Computational and Applied Mathematicians
from Wuppertal, in addition to the Theoretical Physicists.

Project area C is devoted to developing an optimized HPC
infrastructure for the physics program. In 2009, the QPACE (QCD
PArallel computing on the CEll) architecture, based on the IBM
PowerXCell 8i processor, was developed within the SFB. In the current
funding period, Intel MIC (many integrated cores) technology is being
used to develop QPACE 2 and 3, a power-efficient petascale
architecture for lattice QCD and similar applications. The development
team consists of physicists and engineers of the Universities of
Regensburg and Wuppertal and Forschungszentrum Jülich as well as
industrial collaborators.
